Title: Optical adjustment device for copying machine
Inventor: KOJIMA AKIRA
IPC: G03B27/70
Filed: 1994-09-27
Abstract: PURPOSE: To easily execute adjusting work or assembling work and to stably keep a height position after the adjusting work by setting the winding direction of a spring in a reverse direction to the clamping and rotating direction of a screw. CONSTITUTION: Since the twisting direction of the adjustment screw 20a is generally right, the screw is formed in the direction that it is clamped by being rotated clockwise. The winding direction of the spring 21 is left and reverse to the direction that the head of the screw 20a is formed. By rotating the screw 20a, the height of a roof-mirror unit 13 on the other end side is adjusted. Then, the skew of an image is adjusted. When the screw 20a is turned in a loosening direction(counterclockwise) after the adjustment, a compression spring 21 tries to drag in the direction that the twisting thereof is released(loosened). Therefore, since the spring 21 is set in a stretching direction with respect to the looseness of the screw 20a, it functions as the stop of the looseness.

Title: Thermo-sensitive expansion valve
Inventor: ITO YASUNOBU
IPC: F16K31/68
Filed: 1995-09-08
Abstract: PROBLEM TO BE SOLVED: To improve a durability of a diaphragm part at an element segment. SOLUTION: An outer peripheral edge part of a diaphragm 49 is integrally held between a receiver member 55 and a lid member 56 through a ring member 57 in a sandwich form. A supporting fulcrum position where a diaphragm 49 is displaced is set at the inner circumferential end of the ring member 57. Since the ring member 57 has a simple shape, it is possible to form it in an accurate manner like a washer member. Accordingly, the fulcrum point position of the diaphragm 49 when this member is displaced can be positively set at the inner peripheral end of the ring member 57. Since the inner circumferential end position of the ring member 57 is spaced apart from a connecting location A at the outer circumferential end of the diaphragm 49, the diaphragm 49 is hardly influenced with thermal effect caused by welding operation.  Thus, there is a low possibility that a hardness degree of the diaphragm 49 at its fulcrum point position is reduced under a thermal expansion caused by welding operation.

Title: Connecting method of waveguide type optical element and optical fiber for retaining plane of polarization
Inventor: KOMATSU YOSHIROU
IPC: G02B6/34
Filed: 1982-12-24
Abstract: PURPOSE:To provide a simple connecting method between a waveguide type optical element and incident and exit optical fibers for retaining plane of polarization thereof by interposing single mode fibers which are looped so as to be given optical anisotropy in a specified axial direction between the waveguide type optical element and the optical fibers for retainng plane of polarization. CONSTITUTION:When the light wave of either mode of TM or TE is made incident to optical fibers 1 for retaining plane of polarization, a small loop is formed in the main fiber axis direction of the fibers in each single mode fiber used for a single mode fiber array 3 and therefore either mode of TM or TE is maintained when the light wave arrives at the incident end face of a 4X4 waveguide type optical switch 12, whreby switching is accomplished with good efficiency. The change in a polarization direction owing to an exit single mode optical fiber array 9 and exit optical fibers 11 for retaining plane of polarization does not arise and therefore the light wave is emitted in the polarization direction of the incident light.

Abstract: PURPOSE:To secure an error margin at the time of reproduction and to contrive a high density recording by controlling an optical beam output based on a function in which the size of the recording interval on a light memory medium with a writing signal and the writing signal written immediately before is a variable. CONSTITUTION:An optical beam is outputted corresponding to a writing signal 101 supplied to a light memory writing circuit, a recording bit 12 is formed onto a light memory medium 11 by the supplied writing signal 101, and then, the smaller the recording interval is, the smaller an optical beam output is in accordance with the recording bit 12 and the recording bit formed immediately before. Consequently, the dispersion of the size of the bit diameter due to the pre-heating effect due to the heat conduction at the time of forming the bit of the previous recording bit is corrected and the bit formation of an average size is achieved. Thus, the error margin at the time of the information reproduction can be improved.

Abstract: PURPOSE:To improve working efficiency, by a method wherein, in coversion of the direction of a tractor, either of two limit switches, mounted to a hitch, is closed by the interlocking cam of a draw bar, and a direction conversion shaft is moved through operation of a cylinder. CONSTITUTION:In conversion of the direction of a tractor 22, either of two limit switches LS 15, attached to a hitch 39, is closed by an interlocking cam 41 of a draw bar 40 to actuate a cylinder 26. The cylinder 26 located between an axle and a direction conversion shaft is actuated, a limit switch 7 is closed through movement of a slide rod 34, and a working machine 23 also converts a direction. When a handle is started to return, the limit switches LS 15 are both brought into an OFF-state, but the switches are pushed by a central projection 43 of a cam 41 for closing. When a lock groove 35 for straight advance is engaged with an LS 7 through expansion of the cylinder 26, the wheels of the working machine 22 are brought into a straight advancing state. This eliminates the need for a driver to look back each time, and enables sharp reduction of a time required for running-round.
